title: [Comparative assessment of dot-immunoassay and immunochromatography methods for detection of 01 serogroup of vibrio cholerae].
abstract: OBJECTIVE
  Comparative study of sensitivity and specificity of immunochromatographic (IC) assay kit and dot-immunoanalysis for assessment of feasibility of their use for laboratory diagnostics of cholera.
  
  
  METHODS
  Experimental lots of IC assay kit and dot-immunoassay (DIA) for detection of Vibrio cholerae serogroup 01 serovars Ogava and Inaba were constructed on the basis of species-specific monoclonal antibodies (MCA) conjugated with colloid gold (IC) and peroxidase (DIA). Hybridoma-producer of MCAwas obtained and stored in liquid nitrogen in Rostov-on-Don Research Institute for Plague Control. It was deposited in specialized collection of cell cultures of vertebrates in Institute of Cytology (Saint Petersburg).
  
  
  RESULTS
  Strong specificity of IC assay kit and DIA relative to cholera vibrios 01 and absence of crossreactivity with closely related and heterologous microorganisms were shown. Minimal quantity of vibrios, which could be detected using IC assay kit and DIA, was 107 and 105-106 microbial cells respectively.
  
  
  CONCLUSIONS
  Performance of IC assay takes 5-15 min, DIA--1.5 hour, they allow to visually assess the reaction, do not require instrumentation and in perspective both methods could be used on defined stages of scheme for laboratory analysis of cholera.
